Is there a step-by-step instruction of how to set up Sonicwall VPN?

My client is using SonicWall TZ170 and would like to use VPN, but I Googled for a step-by-step instructions and found one from Sonicwall, unfortunately, all it did was kill the Internet access, so I'm looking for something better.

I am assuming this is VPN software client to VPN router, not VPN router to VPN router:
Where did it kill the Internet access, through the router for the various users, or the VPN client user? If the latter it can be an intentional security feature to block local/Internet connectivity while connected to the SonicWall.
Sorry i have no step-by-steps. Which software client are you using, the SafeNet ?

It killed the Internet access through the the router for the various users. The software client we're using is just good ol' Microsoft VPN attachment.

Interesting, sorry I am not familiar with their equipment to help. I am sure others will come along who are. Seems to me SonicWall, if using their VPN solution, uses the SafeNet client, with which I thought I might be able to help to some degree.

Then again, are you connecting to the SonicWall to establish the VPN or a Windows server behind it ,configured as a VPN server. That I my me able to assist with.
If so What O?S version, and how many network adapters on the server. My guess is 2 and you're using Windows server for the VPN. If so RRAS has been modified by your VPN installation, and not allowing users to connect.

I am trying to connect to a Windows server behind the wall.

1 or 2 NIC's

If a single NIC, there is very good instructions on how to configure the server at:
Win 2003
http://www.onecomputerguy.com/networking/w3k_vpn_server.htm
Win2000
http://www.onecomputerguy.com/w2k/w2k_vpn/w2k_vpn.htm
if needed, client:
http://www.onecomputerguy.com/networking/xp_vpn.htm

You also need to configure port forwarding on the SonicWall for PPTP traffic on port 1723, and allow GRE pass through, protocol (not port) 47, which is often an option such as enable PPTP pass-through. I don't have specific instructions for this but the following outlined port forwarding for port 80 on a TZ150 which may be similar. It does not show enabling GRE. On a few routers this is automatic when forwarding 1723.

I off on a service call right now, I'll check back later and see if I can provide more details.

Also please advise if 2 NIC's on the server. If so it would explain why your users lost connectivity. Your routing with RRAS was probably disabled when you installed the VPN server.

hawkeyex,
Have you had any further luck?
If not can you advise if you have 2 network adapters installed on the Windows server?

we have 1. But the server is pretty much FUBAR'ed.. we recommended an upgrade to 2003. we will see if that goes through or not/

Rob WilliamsCommented:
I'll hang tight if you are doing an upgrade, however this sounds like a routing issue which may be carried through with the upgrade. let me know how you make out.

No problem. We got the VPN working.. eventually. But that upgrade is not scheduled for at least until this fall.
